Enthusiast computing refers to a group of people who build high-end personal computers that facilitate gaming, stock trading, video editing, music creation and editing, photograph editing, programming, remote work, cryptocurrency mining, and other hardware-intensive applications. Elements of an enthusiast computer may include cutting edge CPU(s), GPU(s), screen(s), cooling devices, cases, motherboard(s), input devices, computer memory, computer storage, virtual reality headsets, network cards, haptics, power supplies, and peripheral devices. Many manufacturers address this market by producing state of the art offerings which can then be integrated into a custom build. Influence of gaming Games have historically been the driving force behind the rapid pace of consumer hardware development. For example, The 7th Guest and Myst helped drive the adoption of CD-ROMs. Intel and AMD both incorporated instruction sets such as MMX, 3DNow!, and Streaming SIMD Extensions into their processors to support the PC's growing role as a home entertainment device. More recently, however, other types of applications have piqued the interest of computing enthusiasts. Scientific distributed computing tools such as Folding@home, GIMPS, and SETI@home, along with other computationally intensive tasks, including cryptocurrency mining, may also push CPUs and GPUs to their limits, and may also serve as a means of competition, such as tracking how many data sets a user has completed. Costs An enthusiast PC implies the early adoption of new hardware, which is sold at a premium price. As an example, the video card ATI Radeon 9700 Pro was released at US$399 in 2002. Many gaming PCs support the use of multiple video cards in SLI or CrossFire, making it possible to spend thousands of dollars in graphics cards alone. Beyond a certain level of performance, price increases dramatically while offering smaller increases in performance; this is a classic example of diminishing returns. For example, a user who purchased three Nvidia Titan X graphics cards in 2015 would have spent over $4000, while 2016's high-end graphics card offering from Nvidia, the GTX 1080, in three-way SLI would offer a significant increase in performance at less than half the price. Hardware description Case, power supply, cooling, and other case accessories As well as the computing components themselves, case and related accessories often form a target for enthusiast attention, for functional and aesthetic reasons. Computer cases Computer cases, especially of gaming computers, are often selected with care, for their aesthetic and functional value. Functionally, the case must be able to provide
